Question 6 A 4 m long wooden block has to be cut into 5 pieces of equal length. What is the length of each piece?Now, Length of each piece = (𝑇𝑜𝑡𝑎𝑙 𝑙𝑒𝑛𝑔𝑡ℎ 𝑜𝑓 𝑤𝑜𝑜𝑑𝑒𝑛 𝑏𝑙𝑜𝑐𝑘)/(𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑝𝑖𝑒𝑐𝑒𝑠) = 𝟒/𝟓 Making denominator 10 as 5 × 2 = 10 Multiplying and dividing by 2 = 𝟒/𝟓 ×𝟐/𝟐 = (4 × 2)/(5 × 2) = 𝟖/𝟏𝟎 Now, Length of each piece = (𝑇𝑜𝑡𝑎𝑙 𝑙𝑒𝑛𝑔𝑡ℎ 𝑜𝑓 𝑤𝑜𝑜𝑑𝑒𝑛 𝑏𝑙𝑜𝑐𝑘)/(𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑝𝑖𝑒𝑐𝑒𝑠) = 𝟒/𝟓 Making denominator 10 as 5 × 2 = 10 Multiplying and dividing by 2 = 𝟒/𝟓 ×𝟐/𝟐 = (4 × 2)/(5 × 2) = 𝟖/𝟏𝟎 = 08/10 = 0.8 m Thus, each piece is 0.8 m long
